To all whom itmag/ concern:

Be it known that I BERNARD FAYMon vILLE, J r., a citizen ofthe United States, and.

a resident. of Bridgeport, in the county'of F airfield and State of Connecticut, have invented a new and Improved Railway.

Switclnof which the following is a full,

clear, and exact description.

This invention relates torailway switches and particularly to an automatically oper switch which may be operated from. the main line by a contact shoe 011 the engine or by a contact shoe on the engine positioned on the branch line.

Astill further object of theinvention is to provide an automatically actuated switch which is always locked in one position but which is unlockedwhen the mechanismis "mechanism so that a train may be switched olfto the rails 20f the sideline. shoe. strikes'the operatingrailt the same operated immediately previousto the shifting of'the swit'cli' -points.

'In the accompanying drawings: Figure 1- 1311 top plan view of the principal parts of a switch and operatingniecha- 'nism embodying the present invention.

-Referring to theiacconipanying drawings by numerals, 1; indicates the rails of the main line and 2 the rails of the sideline.

Figs. 1 and 2 show the immediate vicinity of a switch together with the switch mechanisinfthe structure shown in Fig. 2 being positioned below Fig. linerely on account of the limitation of the drawings but properly belongs at the right. hen a train is'ap proaching the switch from the rightait will.

.firstreach; the vicinity ofthe switchafter passing point 3. andv if. the. shoe on the en igine is loweredvit will strikethe operating rail i. and depress the same for operating the mechanism hereinafter fully described. The shoe. of the engine may be .of any-kind put preferably of some kind which may be easily raised and-lowered so that when it is graised thclenginewill p'ass the switch with- :out operating the switch mechanism but moves downwardly on. its pivotal mounting and as it moves it compresses thespring 6 (Fig. 10) andinoves the hell-crank lever or system of cranks and shafts 7. 4

As shown in Fig. 9., the cranks and-shafts '-orbell-crank lever structure 7 is operated so that the crank arm 8. is movcd downv wardly' pivotally and the crank arm 9 is "moved: or swung in a vertical plane so as to pull the rod 10 .loi'igitudinally in respectto V the track. 3 The pulling of. the rodl'O 0pcrates the bell-crank lever 11 (Fig. 1) against I the actio-nof spi'ing 12, said bell-crank lever being, pivotally mounted at 13 in a casing 14. The free end of the lever 11 vfits into the slot 15 of a slidingfblock 16 (Figs.

3 and. 1) 'so thatwhen bell-crank-lever. 11 is moved byia'pull on rod 10 the endof the lever will engage the sliding block-16 and move the sliding block against the. action of spring 17. *Thesliding block 16 isxguided by ftll bars 18- and 19 by reason of the fact that therod 20 extends through the. bracket 21 of casing 14 and the fact that the sliding block 16 has a pair of upright spurs 22 straddling the bar 13. Rod is a switch. rod and is ether rigidly or pivotally connected, as desired, to the switch points 23 and 2 1, whereby when the are moved to the position shown in Fig. t the switch will be opened and the train from the main line 1 wiil be switched on to the side line 2.

The rail i is made of such a length as to v be suiliciently near the flange operated rail so that the flange of one of the wheels of the engine will he the rail 25 before the ice on the engi will leave rail This is to allow the operation oit means hereinafter described which will maintain the switch pen until the entire train has moved on to the side line 52. When the rail 25 has been depressed the flanged rail will also be deis merely a sub-shaft for providing a pivotal connection and thereby cause the rail to remain in a horizontal position, but the shaft extends vertically, as shown in Fig. 1, and is journaled in. a bracket 32. An

the last wheel has passed ofl the r il 26.

arm 33 is connected ri idly with shaft 30 and pivotally connected with the link 3% so that when the shaft 30 rocks link Sl'Wlll be given a push and the swinging bar 31 will be moved pivotaily in a horizontal plane. The link and. also links 85 and 36 are connected with bar 31 by suitable bolts or other means extending through the slots 3? and 38, said slots being provided so as to allow a proper adjustment of the parts, though an ordinary round aperture will be sufiicient.

W hen the bar 341: given a shove links 35 and 36 will be given a pull, link 86 operating the bell-crank lever 39 while link 35 operates an arm 40, which arm is rigidly secured to shaft e1. i ihaft ll is mounted in a suitable bearing (Fig. 9) and the shaft is rigidly secured arm pivotally connected at at to the rail 26. An idle pivotally. mounted arm is. also provided, as shown in Fig. 9, for maintaining the rail 26 parallel. By this means, when the rail 25 has been de aressed motion will be communicated to rail 26 for depressing the same and, consequently, when the last wheel has left rai 25 said rail will remain depressed until A as just described will pull on the link move the bell-crank lever 39 against the action of spring 4-1) for moving the sliding block 16, the end of one of the arms of bellposition shown in Fig. 1, by reason of the fact that the lock t? pivotally mounted at %8 will prevent the block 16 from sliding. F or this reason the bell-crank levers 11. and 89 strike the curved sides or earns 19 and of the locking member 17 and raise said lock,

as shown in Fig. a, after which the block may be freely moved for opening the switch. in case a train should approachthe switch from the side track, the rail 26 will. first be depr ised and bell-crank lever 39 operated for throwing the itch, whereas if the train approached the switch from the main line bell-crank lever 11 would be operated. As shown in Fig. 10, the rail 4 is returned by spring .6 while the rails 25- and 26 are returned by suitable springs 51 and 52, as shown in Figs. 3 and 7, whereby when the train has passed the switch will. automatically resume its closed and locked position. The return of the switch is assisted by. the spring .17. In order to prevent an excessive return a substantially U-shaped member 7 is pivotally connected to wire at and straddles the supporting bracket 9, said U-shaped member having a slot therein for accommo-x dating the limiting pin 8.

What I claim is:

1. In a device of the character described, the combination with a switch, of a rod connected to the switch for shifting the same, a sliding block connected with said rod, a spring acting on said sliding block for bold ing the same and said rod in such a position as to maintain the switch closed, a pivotally mounted locking member engaging said block and locking the same against movement in one direction whereby said switch is locked closed, cams arranged on said locking member, and means for moving said block formed so as to engage said cams and operate the same for disengaging said lock immediately previous to the movement of the block.

2. In a device of the character described, the combination. with a switch, of a rod for operating said switch, a sliding block con-' nected with said rod, a pair of bell-crank levers acting on said block for sliding the same and moving said rod for opening the switch, a locking member formed with cams for normally locking the block against movement, said cams being positioned so as to engage the bell-crank levers before the bell-crank levers engage the block and means operated by a tram passing over the swltch for moving said bell-crank levers.

3. In a device of the character described,-

ing block, said lock being provided with a pair of curved cam members, a bell-crank lever on each side of said block having one end extending into the slot in the block, and means automatically actuated by trains passing over the switch for moving said bell-crank levers whereby the first movement will cause the bell-crank levers to pass to the bottom of said slot and simultaneously engage said cams for disengaging said Y ment of the block from operating said rod,

a cam on'eac'h side of said pivotally mount ed lock, and a pairof bell-crank levers exgage said cams and move the same to said. block out of the path of movement of said projections and then move the block and rod until the switch has been opened.
